Another approach would be to keep your own index of blocks and use that for the data reads. Since fdelete and fzero wont actually relayout the files in order to make the data linear (even if such calls existed) there isnt much point performancewise doing it in kernel space - its a very specialised application - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
